    • A brushless motor driving circuit includes a deviation detector for receiving a PWM input signal, which issues an instruction for rpm control, and detecting a deviation from duty ratio 50% of the PWM input signal, a determiner for detecting a comparison result at a threshold of duty ratio 50%, and a PWM output circuit for receiving a PWM reference signal having a duty ratio 50%, and producing a PWM driving signal, to be used for driving a brushless motor, in response to the deviation and the comparison result. The PWM driving signal is produced by adding the deviation to the PWM reference signal when the duty ratio of the PWM input signal is over 50%, and by subtracting the deviation from the PWM reference signal when the duty ratio is less than 50%.

    • A vibration motor obtains a FAST signal when r.p.m. of the motor is faster than reference speed, whereby an output-driving circuit is controlled by the FAST signal to omit parts of the powering periods of respective phases. The motor thus controls the r.p.m. and increases torque ripple generated from the motor. As a result, vibration magnitude increases and insufficient vibration due to downsizing of the motor can be compensated by the control system. A motor driver can be formed with a one chip semiconductor device, so that the number of exterior components is reduced and the motor can be downsized and have light weight
    • 当r.p.m.时,振动电机获得FAST信号。 的电动机比参考速度快,由此通过FAST信号控制输出驱动电路以省略各相的供电周期的部分。 因此,电机控制r.p.m。 并增加从电机产生的转矩波动。 结果,振动幅度增加,并且由于电动机的小型化引起的振动不足可以通过控制系统来补偿。 电动机驱动器可以由单芯片半导体器件形成,从而减少了外部部件的数量,并且可以使电动机的尺寸减小并且具有较轻的重量
